Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

✗
Configuring system-wide kernel sysctl parameters for container networking.
Why it's wrong here
sysctl settings are managed via sysctl, not podman system commands.

Why this is correct
podman system df reports disk space usage.
✓

Why this is correct

Why it's wrong here
Container updates are handled via auto-update or systemctl, not podman system auto-update directly.

Why this is correct
podman system prune removes unused data.
